ZF 0730.007.760 SHIM | OEM Genuine Part

Overview

The ZF 0730.007.760 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within the final drive assembly of heavy-duty construction machinery transmissions. This thin, hardened steel shim sits between the differential housing and the bearing journal, allowing technicians to fine-tune gear backlash and preload during assembly or overhaul. The SKU 0730.007.760 is a factory-specified part that ensures the differential and axle bevel gear mesh operate within ZF’s strict tolerance windows, preventing premature wear on adjacent components such as the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING.

Symptoms of Failure

When the ZF 0730.007.760 shim loses its original thickness due to wear or corrosion, the following failure symptoms typically emerge:

• Excessive gear backlash in the differential: A noticeable “clunk” when shifting between forward and reverse, often accompanied by a dull metallic impact sound from the axle housing.
• Premature taper roller bearing failure: Incorrect shim thickness alters bearing preload, leading to overheating, rough rotation, and eventual seizure of the 0750117075: TAPER ROLLER BEARING.
• Oil contamination from metal particles: As the shim collapses, the 2093209023: DIFFERENTIAL gears grind against the housing, shedding fine metallic debris into the transmission fluid.
• Vibration during low-speed operation: Loose axial clearance allows the differential assembly to shift under load, causing a rhythmic shudder felt through the chassis during maneuvering.

Compatibility

This shim is primarily used in ZF’s WG series powershift transmissions found in wheel loaders, graders, and telehandlers. Based on its dimensional profile and application, the 0730.007.760 is compatible with the following ZF transmission models:

• ZF WG180
• ZF WG200
• ZF WG210
• ZF 4WG-200 (early variants)

It is installed directly against the 5838300626: DIFFERENTIAL HOUSING to set the correct position of the 2093209023: DIFFERENTIAL assembly. Always verify the existing shim stack thickness before replacement.

Frequently Asked Questions

Q: Can I reuse the 0730.007.760 shim after disassembling the differential?
A: ZF recommends replacing this shim with a new OEM part during any overhaul. The shim compresses slightly during service, and reusing it may lead to incorrect preload on the taper roller bearing.

Q: How do I measure the correct shim thickness for my ZF WG200 transmission?
A: Use a dial indicator to measure the axial play between the differential housing and the bearing race. Subtract the desired preload (typically 0.05–0.10 mm) from the measured gap to determine the required shim thickness. The 0730.007.760 is a 0.76 mm shim; you may need to stack multiple shims to achieve the exact specification.

Q: Is this shim compatible with the ZF 4WG-310 transmission?
A: No. The 4WG-310 uses a larger differential housing and requires a different shim diameter. Always verify compatibility with your specific transmission model before ordering.
